Lee's Pet Products ALE12405 Check Air Flow Valve for Aquraium Pumps, 1-Blister Card

Bought for a project on an under-sink soap dispenser that kept loosing its prime. Kept soap in tube rather than flowing back into soap bottle as expected. Works as advertised, check flow. Buy one, or two........recommended.

First off the air in side is nice and tight however the outlet side is loose, bought 2 of these 1 broke trying to remove the air inlet hose so I had to super glue it back together the air outlet side is so loose that your hose will fall off half the time. Not worth the cost, going to try some other ones.
